JOHN K. LEEDY, OF TOMS BROOK, VIRGINIA.

'COMPRESSED-AIR WATER-ELEVATOR.

@PECIIEICATION forming part of-Letters Patent No. 298,990, dated May 20,18184.

l Application filed February 5, 1884. (No model.)

To all whoml it may concern:

Be it known that I, JOHN K. LEEDY, a citizen of the United States,residing at Toms Brook, in the county of Shenandoah and State ofVirginia, have invented certain new and useful Improvements inCompressed-Air Water-Elevators, of which the following is aspecification, reference being had therein to the ac# companyingdrawing.

This invention has for its objects to provide certain improved mechanismwhereby water may be elevated from wells or other sources in an easy andconvenient manner. These objects I attain by the means illustrated inthe accompanying drawing, in which is represented a View showing myinvention partly in section and partly in elevation.

In the said drawing, the letter A indicates an air-forcing pump, and Ban air-reservoir, connecting with the pump A by means of a pipe, O. 'Ihesaid reservoir is represented as spherical in the present instance; butit may be of any other suitable shape, and is provided withasafety-valve, I), of the ordinary description. From the said reservoirextendsahorizoutal pipe, E, which is provided with stopcocks F G, andfrom said pipe, at a point between the stop-cocks, extends a verticalpipe, H, down into a well, I. The pipe H, at its lower end, connectswith the upper part of a chamber, K, locatedin the lower part of thewell, and provided with a perforated inlet, L, and inwardly-openingvalve M. From the lower part ofthe water-chamber extends a service-pipe,N, which is designed to convey the water to the proper point or pointsof delivery. The said pipe is provided with a stop-cock, I), by means ofwhich the discharge of the water may be regulated.

The operation of myinvention is as follows: Air is forced into theair-reservoir by means of the air-pump, the cock F being closed and thecock R opened until the pressure raises the safety-valve, which isdesigned to prevent the explosion of the reservoir. The stop-cocks R andG are then closed and the cock F opened, which permits the compressedair to enter the chamber K and exert a pressure upon the water therein,which has previously entered through the inlet below. The pressureautomatically closes the valve, and, finding no other escape, isdischarged through the service-pipe upon opening the cock at its upperend. When the water from the chamber is exhausted, the cock Gis opened,which allows the chamber to fllwith water, when the operation isrepeated.

Having thus described my invention, wh at I claim, and desire to secureby Letters Patent,

The combination, in a water-elevator, of an air-pump, an air-chamberconnected thereto by a pipe provided with a stop-cock, said airchamberhaving a safety-valve, a water-chamber connected to the air-chamber,said connection having an inlet and outlet stop-cock, and thewater-chamber having a water-inlet properly valved, and an outlet-pipefor the water, also provided with a stop-cock, all the parts beingarranged to operate as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN K. LEEDY.
